Completed Technology Project

Project Introduction

A Nanotechnology Approach to Lightweight Multifunctional Polyethylene Composite Materials for Use Against the Space Environment, Phase I
Polyethylene-based composite materials are under consideration as multifunctional structural materials, with the expectation that they can provide radiation shielding, micrometeorite shielding, and pressure containment during interplanetary missions. While ultrahigh molecular weight polyethylene (UHMWPE) is the hardest known thermoplastic, its impact strength and wear resistance still pale in comparison to many other known materials. We propose composites of UHMWPE with these materials, with the expected outcome of increasing its ability to perform as a micrometeorite shield. More »
